Chemicals such as formaldehyde and potassium carbonate that are used in the production of plastics such as PEEK, POM, PTFE, and PVDF can be produced with captured carbon dioxide instead of fresh carbon feedstock.
Regulatory authorities in Singapore have made efforts to support the growth of PPVC as a preferred DfMA approach.BCA now mandates the use of PPVC on many types of residential Government Land Sale (GLS) projects and has established an acceptance framework backed up by the PPVC Manufacturer Accreditation Scheme.. BCA have promoted potential benefits of PPVC including improved productivity (up to 40% manpower and time savings), less dust and noise pollution, improved site safety and improved quality control in a factory environment..
There are now several recognised PPVC project success stories in Singapore, including the.Crowne Plaza hotel at Changi Airport.Brownstone condominiums.
However, BCA also notes that PPVC currently attracts a cost premium of just under 8% compared to.reinforced concrete construction.
, driven by a range of factors including comparatively low supply and demand.. Singapore has shown a great commitment to achieving the advantages of DfMA but PPVC has been more successful on some projects (and some types of project) than others.
A local mindset has been established that equates PPVC with Design for Manufacture and Assembly at the expense of alternatives.You could say that we have learned similarly in the building of batteries; replicating and combining small cells works much better than trying to create large cells.
The body itself carries on the advantages of scaling.An organ contains some hundred billion cells and the body is made up of about 100 organs and limbs..
If we look more broadly into the living world, we can see that size and scale are really important factors in function, efficiency, and survival.Human beings are not accidentally the size we are.
